WATER SEAL ron GAS RETORTS.

Application filed November 2,1918. Serial No. 260,839.

To all whom z'tmay concern Be it known that I, ARTHUR W. WARNER, a citizen of the United States of America, and resident of Media, in the county of Delaware and State of Pennsylvania, haveinvented a certain new and useful Improvement in Water Seals for Gas Retorts, of which the following is a trueand exact description, reference being had to the accompanying thereof. a

.My invention relates to the manufacture of gas in retorts and has for its object to provide improved means for sealing the con nection between the retort and its standpipe when it is desirable that this connection. should be closed. A further object of my invention is to provide for the feeding of a liquid into the lateral connection between the retort and standpipe in a .way well adapted for cooling the issuing gas and for rapidly filling the liquid seal which I use for closing the retort.

Heretofore valves of various forms have been used for closing the lateral connection between retorts and standpipes, and have been found to give more or less trouble in use.

My invention, broadly speaking, consists in providing water sealing mechanism in the lateral connecting the retort and standpipe, the shifting of a movable member of which will establish the water seal or allow it to flow out and open the connection to the standpipe. The nature of my improvement will be best understood as described in connection with the drawing in which- Figure 1 is a vertical section through a retort and standpipe showing also in section my water trap and liquid feeding mechanism, and

Figure 2 is a cross sectional view on the line 2-2 of Figure 1.

A is the gas retort having a laterally extending conduit A, which should be downwardly inclined, and, as shown, is formed with a bottom portion A in the form of a segment of a cylinder, the top of this portion being indicated at A The lateral, in the construction shown, is formed integral with the retort mouth piece and secured to the standpipe B by flanges A, the standpipe having a hole B formed in its side in registration with the lateral.

In theillustrated construction side walls,

drawings, which form a part establish the seal." Obviously B of the opening through the the same 3111" ose if brought sufficientlv N .1 l p a raised. Above the slot F outlet port H one of which is shown at A, extend from the sides of the lateral conduit through the opening B, and are formed with inwardly projecting segmental flanges A having the same curvature as the bottom portion A of the lateral v C is a downwardly extending partition extending from the top of the lateral to a point where its lower edge will come below the level of the liquid in the water seal when the sealing mechanism is in position to the top edge standpipe will serve D is a shaft extending through the side of the lateral conduit and actuated by an eX- terior handle (not shown). To this shaft is attached by arms E a dam E having the form of a segment of a cylinder and adapted to move in close proximity with the cylindrical bottom A of the lateral and the flanges A When the dam E is retracted to the position shown in full lines any fluid as well as gas from the retort will flow (freely. from the lateral to the standpipe, and

when swung forward to the position shown in dotted lines the dam and the bottom and sides of the lateral form a cup which will retain any fluid, and with the partition C form a water seal to prevent the flow of gas from the retort. Fluid for filling the water seal may be provided in any convenient way. In the construction shown fluid flowing down the standpipe will obviously be caught and retained in operative, but I prefer to into the lateral conduit.

In the construction shown I form a slot indicated at F across the top of the lateral to permit of a film of fluid being showered across the lateral in the path of the issuing gas and into the seal when the dam is a box G is secured having a chamber G which is divided into a reservoir chamber G and an outlet chamber Gr by a dam G which extends down into slot F, as shown, and is formed with depressed portions 9 g at its top as shown in Fig. 2. An inlet port G leads into the reservoir chamber and is connected to the of a valve box H, having an inlet port H connected to a fluid pipe J, and a seat H for a plug cock I having two ports I and I of different section,

introduce liquid the seal when the dam is Y supply whirh can be turned to registo" with the ports of the valve box, which box has also a waste outlet H which can be connected with the port 11 through an adjustment of the plug cock.

In operation the smaller port I is connected to the inlet and outlet ports and is adapted to furnish to and over the dam a suflicient supply ofliquid to form a film falling across the lateral to cool the issuing gas and maintain a flow of liquid over the retracted dam E of the seal. The recessed portions of the dam edge insure that the liquid distribution shall be fairly equal across the lateral. hen it is desired to close a retort lateral the dam E isturned up to operative position and by preference the cock turned to connect the largerport I down below the top of its'rear wall and movable means operating to dam up liquid in the lower end of the inclined conduit to a height-above the bottom of its front wall.

2. In combination with a gas retort and a standpipe, a downwardly inclined lateral conduit connecting the retort with the standpipe and so formed that liquids contained therein will "flow freely into the standpipe and a swinging cup like dam pivoted in the conduit and fitting against the walls and bottomthereof, said dam being formed as described to permit a free gravital flow of liquid when restricted and to dam up the liquid to .a desired height when swung outward.

3. A gas retort havinga downwardly inclined lateral conduit leading from it in combination with a standpipe into which said conduit opens at its lower end, a liquid supply conduit leading into the lateral conduit, a two-way cock having ports of different section for regulating the liquid supply, and movable means for establishing and discharging a liquid seal in the lateral conduit.

4. A. gas retort having a downwardly inclined lateral conduit leading from it in combination with a standpipe into which said conduit opens at its lower end, a liquid reservoir located at the top of the lateral conduit and discharging into and across said conduit over a dam and meansfor feeding said reservoir with liquid.

5. A gas retort having a downwardly inclined lateral conduit leading from it in combination with a standpipe into which said conduit opens at its lower end, a liquid reservoir located at the top of the lateral conduit and discharging into and across said conduit over a dam having a series of depressed portions at its top, and means for feeding said reservoir with liquid.
